You'll probably get a lot of responses on this one.  I'm currently 
running the i386 FreeBSD on an Ahtlon 64 as my desktop.  I also have the 
64 bit installed on a seperate partition to experiment with.  I have an 
A8V-E mobo that has the K8T890.  Works just fine except an occasional 
glitch while booting freezes the system.  I've read it's an ACPI thing, 
but since I rarely reboot I've not bothered to disable ACPI.

Later,
Micah
